new and useful Im rovements in Non-Refilh, able Bottles, of which thefollowing is a specification.

This invention relates to an improved nonrefillable bottle.

' The im rovement will first be described, and the eatures of inventionwill then be pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a vertical sectionof the neck and upper part of a bottle embodying our inven t1on. Fig. 2is a horizontal section of the neck of the bottle on the line 2 2 ofFig. 1. Fig. 3 is a horizontal section of the plug, which is permanentlyfitted in the bottleneck. This is also on the line 2 2. Fig. 4 is aperspective view, on a larger scale, of the flap-valve and ring-seat.Fig. 5 is a side view of the lug.

The bott e-neck near its base or joinder with the body of the bottle hasan inwardprojecting shoulder a, and above said shoulder the interior ofthe neck has an annular groove 6. In other respects the interior of theneck is straight and smooth like an ordinary bottle. e

A plug a, of porcelain, vitreous substance, or any suitable material,has a cylindric form to fit snugly within the neck. The lower end at ofthe plug in the present instance is of a size reduced from that of the uper portion, and thereby an offset e is forme' By reference to Fig. 1 itwill be seen this offset rests down upon the inward-projecting shouldera, which latter thus supports the plug in the neck. In its constructionthe plug is made in two egual semicylindric parts, each part having a atsurface and the two flat surfaces being in contact or joined,

as indicated by the line f. By constructing the plug in two parts, asdescribed, we are enabled to form a zigzag passage g, extendingentirelythrough from the top to the bottom of the plug. Within thisassage are a lural number of flap-valves or E say from two to five-oneof the valves being secured in each of the straight sections,

which are separated by bends "i. Each valveis hinged or pivoted so as toopen in theout-" ward directionthat is, to open in'a direction that willallow the li uid contents of, the bottle to discharge, ut it' is" to beADIMINISTRATRIX 0F s'AIn fWiI'iLIAMnEW si observed that the alternatevalvesare rev xversely positioned, by which we mean that the lowermostvalve h has'itshingeor pivotat one side of the passage, and the secondor next valve above has its hinge or pivot at the opposite side of thepassage, and the third va ve has its hinge or pivot at the same side asthe lowermost valve, and the fourth or upper valve has its hinge orpivot at the same side of the passage as the second one. By thus havingthe alternate valves in the zigzag passage reversely hinged or pivotedall the valves will not swing open when the bottle is tilted. Some ofthe valves will swing 0 en as a result of merely tilting the bottle; utother valves will remain closed. Of course when the bottle is tilted topour out the li uid the action of the liquid that flows throug thepassage 9 to discharge will open any of the valves that may be closed.

The zigzag passage and the valves distributed between the bends in saidpassage and the alternate valves reversely hinged constitute animpediment that will practically preventthe bottle from being filledthrough the said assage. After the valves have been positionedin theassage the two semicylindric parts of the p ug are placed together andcemented.

The plug 0 in practical o eration will not be fixed in position within te neck until the bottle has been filled will the liquid it is desired tohold. The plug carries one or more spring-pressed bolts k, which projectfrom its cylindric side. Each bolt (in the present instance two)occupies a socket l in the side of the plug, and a small spring in thesocket presses against the end of the olt and causesthe neck. As soon asthe offset 6 at.-the bottom of the plug becomes seated on the shoulder ain the bottle-neck the bolts 7c in the plug will have positioncoincident with the annular groove 1) in the neck, and thereu on thesprings will push the bolts out and t e ends of the bolts will enter thesaid groove 1) and serve to ermanently lock the plug to its position.here is a space in the bottle-neck above the plug a to receive anordinary cork the said annular groove and the cylindric plug to retainthe latter in place.

2. A non-refillable bottle having an annular groove at the interior ofthe bottle-neck; a cylindric plug having a zigzag passage extendingthrough the plug from to to bottom and provided with a plural num er offlapvalvesthe alternate valves having their hinges on opposite orreverse sides, and spring-pressed bolts projecting from the cylmdricside of the said plug and engaging in the said annular groove of thebottle-neck.

In testimony whereof we aflix our signatures in presence of twowitnesses.
